Receptacle closure device having hand grip

ABSTRACT

A receptacle closure device includes a receptacle having an open upper end, and a closure having a top wall and a marginal flange portion bent downwardly from the top wall for engaging onto the upper end of the receptacle. The closure includes one or more hand grips extended from the marginal flange portion of the closure, and each has two ends secured to the marginal flange portion of the closure with connectors, for allowing the hand grip to be folded relative to the closure to carry and lift the closure and the receptacle. The closure includes one or more hinge connectors coupled between the hand grip and the marginal flange portion of the closure, and breakable by users.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a receptacle closure device, and more particularly to a receptacle closure device having a pivotal hand grip for being selectively released from the closure device, and for carrying or lifting the receptacle.

2. Description of the Prior Art

Typical receptacle closure devices comprise a number of helical or thread lugs formed or extended from an upper end surface of a receptacle and spaced away from each other, and a closure including a marginal flange portion bent downwardly from the margin of a top wall and including an inturned wire edge turned upwardly within the closure, for threading or engaging with the thread lugs of the receptacle.

For example, U.S. Pat. No. 2,148,169 to Merolle discloses one of the typical receptacle closure devices comprising a number of thread lugs provided or extended from an upper end surface of a receptacle, and a closure including an inturned wire edge turned upwardly within the closure, for threading or engaging with the thread lugs of the receptacle, and for openably attaching the closure onto the receptacle.

Recently, the typical closures and the receptacles are normally made of plastic or other synthetic materials and formed by molding or mold injection processes. The other typical closures may be molded onto the receptacles, and selectively releaseable from the receptacle, for allowing the typical closures to be opened from the receptacles.

However, all of the typical closure devices comprise a closure that may be used for threading or engaging with the receptacle only, but fail to provide handles or hand grips for carrying or lifting the receptacles.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional receptacle closure devices.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a receptacle closure device including a pivotal hand grip for being selectively released from the closure device, and for carrying or lifting the receptacle.

In accordance with one aspect of the invention, there is provided a receptacle closure device comprising a receptacle including an open upper end, and a closure including a top wall, and a marginal flange portion bent downwardly from the top wall, for engaging onto the upper end of the receptacle, and the closure includes at least one hand grip extended from the marginal flange portion of the closure, and having two ends secured to the marginal flange portion of the closure with connectors, for allowing the hand grip to be folded from or relative to the closure to carry and lift the closure and the receptacle.

The closure includes at least one hinge connector coupled between the hand grip and the marginal flange portion of the closure, and breakable by users, to openably securing the hand grip to the marginal flange portion of the closure.

The closure includes an inner thread extended inwardly from the marginal flange portion of the closure, for threading with the receptacle, and for openably attaching the closure onto the receptacle.

The receptacle includes a lock groove formed in an outer peripheral portion of the upper end thereof, and the closure includes a lock rib extended inwardly from the marginal flange portion of the closure, to engage into the lock groove of the receptacle, and to lock the closure onto the receptacle.

The closure includes a peripheral band located at a lower portion of the marginal flange portion of the closure, and releasably coupled to the marginal flange portion of the closure with a first hinge line, for allowing the peripheral band to be disengaged from the marginal flange portion of the closure by breaking the first hinge line.

The peripheral band includes a second hinge line provided in a segment thereof, to form two parallel narrowed strips, to allow the strips to be disengaged from the marginal flange portion of the closure and the peripheral band by breaking the first and the second hinge lines.

The peripheral band includes a knob attached to either of the strips, to pull and disengage the strips from the marginal flange portion of the closure and the peripheral band.

Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIGS. 1-4, a receptacle closure device in accordance with the present invention comprises a closure 10 including a top wall 11, and a marginal flange portion 12 bent downwardly from the margin or the outer peripheral portion of the top wall 12, for engaging onto an open upper end 41 of a receptacle 40.

The closure 10 may include a typical inner thread 13 (FIG. 4) extended inwardly from the marginal flange portion 12 of the closure 10, for threading or engaging with the corresponding threads or outer thread 42 of the receptacle 40, and for openably attaching the closure 10 onto the receptacle 40.

The closure 10 may further include a lock rib 14 extended inwardly from the marginal flange portion 12 of the closure 10, and preferably located at or close to the lower portion 15 of the closure 10 (FIGS. 2, 4, 5), for engaging into a corresponding lock groove 43 (FIG. 4) that is formed in the outer peripheral portion of the upper end 41 of the receptacle 40, and for locking the closure 10 onto the receptacle 40.

The closure 10 further includes one (FIGS. 5-9) or more, such as two hand grips 20 (FIGS. 1-3 and 10) provided on or attached to or formed on or extended outwardly from the marginal flange portion 12 of the closure 10, and each having two ends 21 secured to the marginal flange portion 12 of the closure 10 with welding or hinge connectors 22, for allowing the hand grips 20 to be folded or bent upwardly and formed as carrying devices for carrying or lifting the closure 10 and the receptacle 40 (FIGS. 1, 4, and 7-11).

The closure 10 may further include one or more further dots or welding or hinge connectors 23 coupled between the hand grips 20 and the marginal flange portion 12 of the closure 10, to openably or temporarily securing or coupling the middle portions of the hand grips 20 to the marginal flange portion 12 of the closure 10, and for allowing the hand grips 20 to be optionally or selectively released and folded or bent upwardly from the marginal flange portion 12 of the closure 10 when the hinge connectors 23 are broken by the users, for example.

In operation, as shown in FIGS. 1, 4, and 7-11, when it is required to carry or lift the receptacle 40, the hinge connectors 23 may be broken by the users, to release either or all of the hand grips 20 from the marginal flange portion 12 of the closure 10, and thus to allow the hand grips 20 to be folded or bent upwardly relative to the marginal flange portion 12 of the closure 10, to allow the receptacle 40 to be easily and readily carried or lifted by the users, without attaching additional handles or hand grips onto the receptacle 40.

The closure 10 may further include a releaseable or openable peripheral band 30 formed or provided or located at the lower portion 15 of the marginal flange portion 12 of the closure 10, and releasably or openably coupled to the marginal flange portion 12 of the closure 10 with a hinge line 31, for allowing the peripheral band 30 to be disengaged or removed from the marginal flange portion 12 of the closure 10 by breaking the hinge line 31.

The peripheral band 30 includes another hinge line 32 formed or provided in a portion or a segment thereof, to form two substantially parallel narrowed strips 33, 34, best shown in FIGS. 5 and 8, and a knob 35 attached to one of the strips 33, for pulling and disengaging the strip 33 from the marginal flange portion 12 of the closure 10 and the peripheral band 30 and the other strip 34, by breaking the hinge lines 31, 32, and thus for disengaging the peripheral band 30 from the marginal flange portion 12 of the closure 10, in order to remove the lock rib 14 of the closure 10 from the receptacle 40, and thus to unlock the closure 10 from the receptacle 40.

The hand grips 20 may be optionally or selectively formed or provided on the peripheral band 30, for allowing the hand grips 20 to be disengaged or removed from the marginal flange portion 12 of the closure 10 together with the peripheral band 30. The closure 10 may include a single hand grip 20 (FIGS. 5-9), or two or more hand grips 20 (FIGS. 1-3 and 10) attached onto the marginal flange portion 12 of the closure 10, to allow either of the hand grips 20 to be optionally or selectively released and folded or bent upwardly from the marginal flange portion 12 of the closure 10 when the hinge connectors 23 are broken by the users. The knobs 35 may be formed into various kinds of shapes, such as those shown in FIGS. 1-3 and 5-8, or as shown in FIGS. 9 and 10.

Accordingly, the receptacle closure device in accordance with the present invention includes a pivotal hand grip for being selectively released from the closure device, and for carrying or lifting the receptacle.
